Still have this set of carbs and head for a 20R. Carbs are Dell'orto 40DHLA with a lot of extras, set up for cable pull. The head is ported with stainless oversize valves, bronze guides and performance springs. Nothing has been installed or used since rebuilding. All for $1700. Central CA location, San Luis Obispo area. Prefer pick up. PM with your number or to get mine so I can send pics.
